Error during transport: Method is not declared + Component missing

March 24, 2014, 12:16 am

HI

I got 2 errors when I transport:

 

Error 1:

Program ZCL_ZGW_VH_ORDER_DETAI_DPC_EXTCP, Include ZCL_ZGW_VH_ORDER_DETAI_DPC_EXTCO: Syntax error in line 000003

Method 'DETSET_GET_ENTITY' is not declared or inherited in class 'ZCL_ZGW_VH_ORDER_DETAI_DPC_EXT'. -

 

Error 2:

Program ZCL_ZGW_VH_ORDER_DE_01_DPC====CP, Include ZCL_ZGW_VH_ORDER_DE_01_DPC====CM006: Syntax error in line 000190

The data object 'LS_ET_DETAILS' does not have a component called 'ZZ_MATR_LEV_DATO'.

 

1)

When I go to Class Builder (SE24), and make a syntax check for ZCL_ZGW_VH_ORDER_DETAI_DPC_EXT, I got the error:

Class ZCL_ZGW_VH_ORDER_DETAI_DPC_EXT,Protected section

Method "DETSET_GET_ENTITY" is not declared or inherited in class

"ZCL_ZGW_VH_ORDER_DETAI_DPC_EXT". -

 

The code looks like this

 

protected section.  methods DETSET_GET_ENTITY    redefinition .

 

 

 

2)

If I go to include ZCL_ZGW_VH_ORDER_DE_01_DPC====CM006 (in SE38), I am navigated to method: DETSET_GET_ENTITYSET (That was the missing method in error 1). When I do a syntax check, I got the error message:

Class ZCL_ZGW_VH_ORDER_DE_01_DPC,Method DETSET_GET_ENTITYSET

The data object "LS_ET_DETAILS" does not have a component called

"ZZ_MATR_LEV_DATO".

 

Then I double click at ls_gw_et_details-zz_matr_lev_dato, and got the data statement: DATA ls_gw_et_details LIKE LINE OF et_entityset.

When I double click at et_entityset, I see that the et_enityset is type ZCL_ZGW_VH_ORDER_DE_01_MPC=>TT_ORDDET. Now I double click at TT_ORDDET I got the public section, where I can see that ZZ_MATR_LEV_DATO is already specified.

 

     ZZ_SPORSP_DATO type D,     ZZ_KSTROM type STRING,     ZZ_KSTROM_DATO type D,     ZZ_MATR_LEV_DATO type D,  end of TS_ORDDET. .  types:
TT_ORDDET type standard table of TS_ORDDET. .

 

 

 

Anyone who will help me?

 

Thanks

Dears,

 

I am having problems to add some registered external programs at SMGW.

 

I have two RFC (TCP/IP) connections with the error message "ERROR: program XXXXXXX not registered"

 

I tried to add them by the expert functions, external security editor of files reginfo and secinfo but it didn't work.

 

Then I tried editing the files manually following this instructions but I still get the error: https://help.sap.com/saphelp_nw73/helpdata/en/e2/16d0427a2440fc8bfc25e786b8e11c/content.htm

 

The kernel version is 720 so I can't try the rfcexec.

 

Any other way to register those programs?

 

Thanks for your help!

 

Have a nice day!

The service was running without any problems, but then I wanted to add 2 fields.

I tried to add the fields in the properperties of my entitytype, and do a mapping.

But got an error. So I did remove the fields from the properties again.

Now I got the above error?

 

Anyone who can help me?

Gateway System Aliases

Hi Gurus,

 

I've created a service on the DEV system, and after I've tested it I transported it to the PRD system.

 

In my GW system, trx "/IWFND/MAINT_SERVICE", I found that that my service exists and that I can connect to the PRD systen by deleting the DEV alias, and adding the PRD alias.

 

My question is: Can I keep both aliases set in the gateway system and change between them from the gatewaw link?

 

Here is a print screen with my alias set:

alias.jpg

And here is a print screen of the gateway request URI:

 

client.jpg

 

Is there a way to achieve this ?

 

Thanks,

Dear all,

I have created a OData service and consumed it successfully. I was able to post data to it. Now after altering the "model class" i.e., adding one property and changing ABAP Dictionary type. After doing these changes but i couldn;t consume the service and get "500 Internal server".

 

Did anyone experience this problem? Please note i didnt use Service builder(SEGW) to create a project instead i did all manually using Model and Data provider classes.

 

Please suggest. Your help is appreciated.

Special Characters are getting added after RFC call

Hi,

 

We are calling an RFC in Get_EntitySet method of a Gateway service. In the table 't_output' of that RFC, we have a 'description' field of char50 which is initially blank and gets populated after RFC execution.

But after RFC call in gateway, this field is getting populated with preceding string "   \u0000\u0000\u0000\f\u0000\u0000ఀ"(as found in http response, find the debugger values in screenshot) then the actual values. I have tried executing the FM separately but there it was returning correctly (without this special character string).

Why is this happening and how to resolve it?

Locking mechanism in SAP Gateway.

Hi ,

    I am new to SAP Gateway. I have a scenario where i will get a record from the backend custom table ex:Lets assume a student mark details. The user can change the students mark in the Ui5 screen and then on the click of submit. The record will be updated in the backend .

 

My question is since we are changing the data in the table, who can we handle the locking mechanism in the SAP Gateway when the record is in process.

 

Since i will read the record by using one RFC and update the record by using another RFC.

 

 

Inputs needed on this. Thanks in advance.

Hi Experts,

 

I am new to NW Gateway and working on the IDES NW7.31 with basic NW Gateway components. It seams no patch applied. all of the Gateways components SP levels are Zero.

 

I am not sure why i can't see the Odata service in SICF.

 

Also when i am generating the service using transaction /IWFND/REG_SERVICE using system alias as LOCAL ( with 'NONE' RFC destination) it tries to open the service with wrong host name and port.

 

http://id3tdc00.wdf.sap.corp:55080/sap/opu/sdata/sap/ZBANK01?sap-client=800&$format=xml

 

When i open any webdynpro application, or NWBC i can see the correct host and port which is http://mysapides.mac.com:8002...

 

Netweaver Gateway is also Activated in SPRO.

 

I am not sure what are the changes required to get the Service working on my host.

 

Please suggest.

 

 

Regards,

Nik

Process $batch request also as batch in backend?

April 7, 2014, 2:12 am

Hi,

 

lets assume we have the following scenario: In the (SAPUI5) frontend a user marks 200 record and hits a button that triggers an OData batch request to NetWeaver Gateway. In the backend the request calls some external service (where establishing of the connection might take some time).

In the "standard" behaviour of NetWeaver Gateway all the 200 requests will be processes seperatly in the backend (which - in our case - means 200 seperate calls to the external system).

Is there a way that I can collect all 200 requests at once and send them in one go to the external service resulting in only one call to the external service? (Of course the response returned to the UI depends on what the external service delivers...)

 

Thanks in advance!
