Function Module SO_CONVERT_CONTENTS_BIN

Hi all,

I need advice about my problem.

I need Function Module SO_CONVERT_CONTENTS_BIN but in SAP R/3 Version 4.6C the FM doesn't exist.

I read the documentation the FM release at 50A.

So anyone can tell me other FM that have same function like SO_CONVERT_CONTENTS_BIN or there's any solution for this case?

Thanks

Rio
