Tables using LIKE may only reference flat structures

Question

I wanna have a table parameter in a RFC function module of type CGPL_TEXT1, which uses the domain type TEXT40, which is a char 40.

I tried to create it:

IT_PARTS_DESCRIPTION LIKE CGPL_TEXT1

But I keep getting this error

tables using like may only reference flat structures

I am also not able to use TYPE. If I do so, I get this error:

Flat types may only be referenced using LIKE for table parameters

Answer 1

Don't go there. For RFC-enabled function modules, always use a structure as a line type for your table. The RFC protocol itself also supports unstructured tables, but many adapters don't. So you should

• declare a data dictionary structure Z_MY_PARTS_DATA with a single field DESCRIPTION TYPE CGPL_TEXT2
• declare a data dictionary table type Z_MY_PARTS_TABLE using this structure
• use that table type in your function module.

Answer 2

Look inside the dictionary for a table type which has only one column representing Your Text. If You cannot find it, just go the proper way and define a z structure and a z tabletype based on that structure. This is the proper way and I also prefer to use this ( even sometimes, when I would not really need it, i do this ).... because the structures sand table types can be documented.
