ERROR : LOOP CANNOT BE ASSIGNED TO ANY FIELD.

1) CAN U EXPLAIN THE PAI & PBO IN THIS PROGRAM.

2) EXACT POSITION OF THE LOOP IN THE PROGRAM.

3) WHY I USED THE CURSOR K1 IN THIS PROGRAM.

4) WHAT IS THE O/P ?

5) IF I ENTER THE KUNNR THEN AFTER PRESSING DISPLAY THEN OTHER FILEDS WILL APPEAR.IS IT SO?

Hi,

When you are using the TABLE CONTROL on your screen you have to write LOOP ENDLOOP statements, because a table control you will populate multiple records. that is a must.

but where as you are using just fields, so no need of writin the loop endloop in PAI and PBO.

PROCESS BEFORE OUTPUT.

LOOP AT ITAB CURSOR K1.

MODULE STATUS_0100.

ENDLOOP.

PROCESS AFTER INPUT.

LOOP .

MODULE USER_COMMAND_0100.

ENDLOOP.

remove the highlighted ones

reward if useful.

regards,

Hi,

Why you need internal table for KNA! fields, one KUNNR will have one Name only.So just take a structure, remove that occurs 0 from internal table.

Declare the same fields on the screen ie. structure fields. it will display the Name field on screen.

1)first of all write the MODULE STATUS_0100 and usercommand modules before and after the loop respectively for pbo and pai . loop end loop is used while filling a data from an internal table to a table control to display the fields. so plz use loop endloop only wth table control . as u have to fill ur table control with each line of internal table that is y we use it . in ur case ur looping to internal table to a particular cursor position .

2)position of loop

pbo

MODULE STATUS_0100.

LOOP AT ITAB CURSOR K1.

endloop .

pai

LOOP .

ENDLOOP.

MODULE USER_COMMAND_0100.

for rest of ur questions please be clear with the scenario ur workin in for displaying the data ie ru using a table control or somethin else to display data in
