Perform statement

Hi Experts,

There is a Perform statement in SAP 4.5b:

PERFORM 2150_FIND_COUNTRY/CAT_PC.

So when we replicate this into ECC version it throwing error like:

Syntactical Error:The "/" chacater is reserved for identification of namespaces . It must be entered twice . The name of a namespace must be atleast 3 characters long.

So we changed to PERFORM 2150_FIND_COUNTRY_CAT_PC.Then it worked fine.

But is it the way to do it?..How can we know that this Perform statement is used in how many and what programs?..

It should not effect to allother pgms which calls this Form.

I know Where used list for Prgram but not for Perform Statement.

Regards

Ravi,
