CAMA_DEPENDENCY_MAINTAIN - Char limit

Hi Gurus!

I'm using FM CAMA_DEPENDENCY_MAINTAIN to update/create objects dependencies for my boms.

I'm facing now a problem: i cannot upload dependencies with source longest than 50 chars!

The SOURCE table of FM accepts sources up to 72 chars, as standard sap transaction, but when i try to update them, they are trunked!

I'm working on ECC 6.0 and i looked for some Sap Notes but nothing seems to help me.

Have you any suggestion?
