Patch creation

Hi pros,

How to avoide data loss during patch creation and enabling?

Yeasterday we have deployed a development solution which adds several fields to Customer BO. Everything worked fine, but today client insisted on adding one more field into the system.

So I created a patch to transfer this change in productive system. It seems that every field in the solution were deleted and recreated in the patch. After enabling the patch in test system I can't see any data in fields created in the original solution any longer.

Is this a normal situation with SDK and C4C? Or is there a way to avoide such problems?

Best regards,
