Conversion of SAPSCRIPT to SMARTFORMS

SAP provides a conversion for SAPscript documents to SMARTforms.

This is basically a function module, called FB_MIGRATE_FORM. You can  start this function module by hand (via SE37), or create a small ABAP which migrates all SAPscript forms automatically.

You can also do this one-by-one in transaction SMARTFORMS, under 

Utilities -> Migrate SAPscript form.

You could also write a small batch program calling transaction SMARTFORMS and running the migration tool.
