Thanks Juergen. We ll check the trace and translations as you suggested.
The print program of other forms not passing the language to docparams while calling adobe generated FM as this is optional paramter. The print program of invoice forms sets this language by fetching it from NAST-SPRAS.
Recent we have upgraded the support pack from 5 to 16, SAP EHP1 of SAP NW 7.0. This behavior occurs only after this support pack upgrade. And we debugged the quality system (where upgrade has not yet been done) by allowing it to make changes. Changes are reflecting irrespective of form language. i.e. I changed the static text in form layout and passed the language 'S - Spanish' and it reflects successfully in the output.
Thanks
