Can I Use IIF formula in this case

Hi

I'm trying to find a solution for this issues

ACCOUNT      CUSTOMER     PRODUCT     DATA TYPE          VALUE

VXXXXXX          7566               CSI                      QTY                    300

VXXXXXX          9999               CSI                       QTY                    400

VXXXXXX          9999               CON                    QTY                      100000                             

VZZZZZZ          7566               CSI                       %                          0,05

VZZZZZZ          9999               CSI                         %                         0,10

The % is linked with the Quantity and Product

I need to copy the 300 and 400 in an other account but I don't want the 100000 because I have no % for the PRODUCT CON. IF product is same in compte VZ... and VX... I nned to copy the 300 and 400 in another account not the 100000 same logic I don't have code CON in account VZ for the Customer

Can I use a IIF statement ? And if yes how can I code this in a script ?
