FORMs STRUCTURE option

Former Member — Mon, 30 Jun 2008 09:19:16 GMT

I understood that, in order to manipulate fields from an internal table or record passed as a parameter to a given form, you have to include STRUCTURE [table / struct name]. I wonder how would it be possible to have a program that decides, dynamically, amongst several possible table parameters - if we indeed have to have the STRUCTURE hard-coded, would such a thing be possible ?

Example:

FORM TEST      TABLES P_ITAB STRUCTURE BSEG	
	                USING P_REC STRUCTURE WS_REC.

In the above excerpt of code, it is known beforehand that the table is of the BSEG type. Imagining a scenario where I would only have this information at run time, would it be possible to determine the structure of the table ?

Thanks

if you don't have to know field names, you can use this simple solution:


FORM TEST      TABLES P_ITAB
	                USING P_REC STRUCTURE WS_REC.

FIELD-SYMBOLS: <itab> TYPE ANY.

LOOP AT p_itab ASSIGNING <itab>.
  MOVE-CORRESPONDING <itab> TO p_rec.
ENDLOOP.

ENDFORM.

you can still assign a field of <itab> but you have to do it for each field with ASSIGN COMPONENT

if you have a lot of named fields to use then you can map the input parameter into a local table with the structure you need
