Pricing Routine

Hi All,

I am trying to add some code to a newly created custom routine.

Only for a selective range of customers  - say "1000" to "1790" I want to append the delivery numbers.

Something like this:

IF VBAK-KUNNR in ( RANGE OF CUSTOMERS )

THEN APPEND LIKP-VBELN.

What is the most efficient way of selecting the range in the IF condition without hardcoding?

Any ideas.

Thanks,

Meghna
