validating data

[Former Member]

hi,

question is my selection screen consists of some mandatory fields aong with other fields. mandatory fields r fiscal year,period,company code,Account no.,WBS element.i am populating these fields along with other fields in a field catalog. when i execute the program with the test variant its gives the list display. the data which is displayed in the list is populated in a ztable. when i again run the program with same test data and try to execute it i should give an error message saying "ztable already consist this data u cannot update it again". Message will be triggered only when all the 4 fields (Fiscal year, Period, Company code and WBS element match).

here fiscal year, company code and wbs element fields r parameters where as period is a select option.

for example my ztable consists some records with the data

comp.code period fiscalyear wbselement

from to

1001 10 12 2007 T-010139-1001GBR-VS-EN-D

so when i give in the selction screen the following data error message should get triggered

1001 1 10 2007 T-010139-1001GBR-VS-EN-D

since period 10 record has already been updated in the table.

Error Message will be triggered only when all 4 conditions are satisfied

in the same way we need to check for all the four fields.

i am getting the logic please help me out

Hi

In ZTABLE declare four fileds as key fields..

den while inserting into ZTABLE it will give sy-subrc 4..

Or if u cant make four fileds as key in ZTABLE in program u can validate data before insertion..

do a select using the fileds before inserting into ZTABLE

if already one record exists with key fields den dnt do insert give a error message....

Hi,

First, check if all four fields are defined has key in your table.

if yes, try check with a "select" in your table if informed values just are inserted into your table before to do the insertion.
