How to update a Blanket Salse Agreement(BSA) by grogram in 12.1.3?

Hi All,

I use the public API OE_BLANKET_PUB.Process_Blanket to create Blanket Salse Agreement(BSA), However, this API is only for CREATE not for UPDATE.

-- validation Lines from Process_Blanket API for the blanket header

IF l_header_rec.operation NOT IN ( 'INSERT','CREATE') THEN

   FND_MESSAGE.SET_NAME('ONT','ONT_BSA_BATCH');

   OE_MSG_PUB.Add;

   x_return_status := FND_API.G_RET_STS_ERROR;

   RAISE FND_API.G_EXC_ERROR;

END IF;

I submited a SR for this issue, and got the reply that this bug will be enhanced in a future release.

However, we have an urgent user requiremtne that need to update BSA by current program,
