Hello all,

hi somen,

you can only use LOOP for looping thru the internal table contents.

Yes you can use a loop statement in a program lines node. Are you having a problem? syntax error?

Hello,

Matt and Abdul...thanks for your replies. I am getting this error when I tried the below code in program lines in smartform.

<u>"LS_MAT cannot be converted to line type of GT_MATERIAL"</u>

DATA: ls_mat LIKE gt_material.

  LOOP AT gt_material INTO ls_mat.
    SELECT SINGLE zzcatno FROM mara
      INTO gv_catalog
     WHERE matnr EQ ls_mat-matnr.

    IF sy-subrc = 0.
      EXIT.
    ENDIF.
  ENDLOOP.

GT_MATERIAL is declared in global definition

Try this

DATA: ls_mat LIKE LINE OF gt_material. If it does not work, let us know the definition of GT_MATERIAL.

Hi Somen

What is the type of GT_MATERIAL?

In TYPES (global definitions) I had defined like this.

types: begin of ty_material,
          matnr type matnr,
       end of ty_material,
       lt_material type table of ty_material,
       ls_material type line of lt_material.

And in GLOBAL DATA I defined like this

GT_MATERIAL	 TYPE	LT_MATERIAL

Thanks,

Hi use LS_MAT TYPE TY_MATERIAL.

You can use

DATA: ls_mat LIKE LINE OF gt_material.

or

DATA: ls_mat LIKE ls_material.

or

DATA: ls_mat TYPE ty_material.

Abdul,

I tried but still getting an error.

The error is:

"Field 0 is unknown. It is neither in of the specified tables of declared by 'data' statement"

That is completely different issue. Where is it pointing to in your code? I don't see any 0 in your current code.

Hi

As srinivas said it is completely a different issue.

jus do syntax check at the global data/type declaration and afterwards do it at the program lines as well.

This is completely a different problem...

Thanks for all your replies. My fault. Not because of declarations...old code got disturbed may be due to an accidental key stroke which didnt caught my attention.
