RFC between different SAP Releases

[Former Member]

Hi all,

I want to implement a RFC-Call from one SAP-System to another (ABAP to ABAP) with the SAP standard function module GET_BACKUP_HISTORY_ADA. This uses the internal table BACKUP_HISTORY, which in turn refers to the table SDBAADAHIS. Unfortunately the width of fields in this table varies between different SAP Releases. So if I do the call e.g. from 6.20 to 4.6C I only get a "data-mess" back in my internal table.

I assume this is a rather general problem and there should be solution. Does anybody know?

thanks in advance

Hello Richard,

I don't know if there's a <i>standard</i> way to handle this kind of a situation, but I guess you can circumvent the problem by declaring an internal table with the structure as in the destination system and then use that internal table in the RFC.

I would suggest to use structured string fields. An example will do the trick.

Let say you have a table from your FM. This table Z_SOME_TABLE contains the following fields

- key type char3

- some_struct type char 160

In this field you put all your data.

Then you read your FM and put the result in a work area. The you create a second wa which consists of the real structure od some_struct.

wa type z_some_struct. (=structure of Z_SOME_TABLE)

wb type realstructure (of some_struct).

loop at Z_SOME_TABLE into wa.

wb = wa-some_struct.

write wb-field1.

write wb-field2.

...

endloop.
