Hi,

use CHAIN-ENDCHAIN under PBO event to validate screen field.

code :

CHAIN.
  FIELD : MATNR.
  module validate_matnr.
ENDCHAIN.

 module validate_matnr input.  
    if ych_met-matnr is initial.
      message e000 with 'error'.
     endif.
endmodule.

<b>

select single maktx from <table> into ych_mer-maktx

where matnr eq ych_mer-matnr.

then use FM : DYNP_VALUES_UPDATE to update description field by reading material number</b>

in PAI flow logic

chain.

module ych_met-matnr.

endchaing.

in this module you can write a logic to check whether it exits or not.

Hi,

If your selection criteria depends on the material number, make the screen field as obligatory.

Now, in the PAI do the following on the flow logic.

FIELD YCH_MET-MATNR MODULE TEST.

Save ur program and double-click on the Module name TEST, system automatically creates the module in your program.

MODULE TEST.

Select single matnr from mara where matnr = ych_met-matnr.
if sy-subrc <> 0.
message ....'ENTER VALID MATERIAL NUMBER' TYPE S
endif.

endmodule.

This should solve ur problem, reward points if convinced.

hi

you can fetch the material description from the table MAKT based on MATNR in the PBO Event of the screen.

Note you need to press the enter or carry out any PAI Activity after entering the material number in the MATNR field..

Hi,

In the PBO write the following code :

if ych_met-matnr is not initial.
Select single matnr from mara....
if sy-subrc = 0.
select single maktx from makt into ych_met-maktx
where matnr = ych_met-matnr and spras = 'EN'.
endif.
endif.

Reward points if problem solved.
