Doing TECO / CLSD without using BAPI

Hi Expert,

In my requirement, there are some logic check on the consistency of some fields before doing TECO / CLSD the works order.

I have encounter a problem that the system is too old to have the bapi IWO_AER_DL_ORDER_TECO or BAPI_ALM_ORDER_MAINTAIN.

So i would ask....

1. Is there any risk to update the SAPKW70017 package to produdction server?

2. Is there any alternative way that I can do the TECO or CLSD in a background mode manner? besides the auto TECO options ?

3. Any non-ABAP way if possible?

(since I don't know how to insert the logic in that auto process).
