Multiple performs with tables calling same form

[ricky_shaw]

Hi,

I have 3 different internal tables with DIFFERENT structures with respective work areas (wa).
Say :
itab1, wa1
itab2, wa2
itab3, wa3.

These internal tables are appended based on different scenarios.

I want to build a common FORM subroutine to display the result of itabs via different performs  like below

perform assign_invoice tables itab1 using wa1.
perform assign_invoice tables itab2 using wa2.
perform assign_invoice tables itab3 using wa3.

form assign_invoice tables xtab using wa.
data: lv_opbel type opbel.

loop at xtab into wa.
lv_opbel = wa-opbel. -->errors out saying wa has NO structure & hence no OPBEL field.
endloop.

endform.

In debug mode, i can see wa having OPBEL. 

The actual  wa1 has opbel as part of the structure.

Can anyone suggest please.

You didn't define a type for WA, hence the compiler doesn't know that it has the component OPBEL.

Example of fix:

ASSIGN COMPONENT 'OPBEL' OF STRUCTURE wa TO FIELD-SYMBOL(<opbel>).

Hi Sandra, OPBEL is just one field in WA1. OPBEL is not available in WA2 or WA3.

WA should resemble one of the entire structures Wa1, Wa2 or wa3 at any given point of time.
