Protoolkit-Drawing dimensions turn purple after using ProAssemblyAutointerchange()

[sKarakuni]

Hi all,

I have an assembly and its associated drawing with same name. I'm trying to develop a toolkit program that replaces assembly component using interchange groups. The assembly updates succesfully, but when I checks the drawing, the dimensions turn purple indicating that the references are being lost. 
But when I try to perform the exact interchange group replacement manually through Creo UI, both the assembly and drawing updated correctly with no issue.

Below is the simplified version of my implementation:

• Modify skeleton and Regenerate the assembly.
• ProSolidRegenerate((ProSolid)asm_model, PRO_REGEN_NO_FLAGS).
• Replace the component using ProAssemblyAutointerchange().
• Regenerate the assembly (ProSolidRegenerate(asm_solid, PRO_REGEN_NO_FLAGS).
• Refresh the model tree ProTreetoolRefresh(asm_model).
• Set the current window to drawing window(ProWindowcurrentSet)
• Activate the drawing window(ProWindowActivate)
• Regenerate the Drawing sheet using ProDwgSheetRegenerate()

I've tried various combinations of sheet and view regeneration, window activation and refreshing API's but to no success. Is there any specific regenerate/refresh sequence required to properly update the drawing dimensions when replacing components using interchange method? Any guidance would be greatly appreciated. 
Thanks!
