Hi,
I used both 11SP9 with MPP 11.0R2 and 11SP11 and MPP 11.0R3. I haven´t seen this error message yet.
But I have to admit we didn´t use Alternates and Substitutes very often.
In 11SP11 and MPP 11.0R3 I can confirm that Alts and subs are displayed but sometimes the table rendering of the ProcessPlan makes some trouble when using more than one Alternate Part. But I think this is more related to my customized renderings and stylesheet.
The Method mpp_getPartAlterSubs defenitely changed from R2 to R3. The R2 version has 54 lines of code, the R3 version only 21.
Best regards
Angela
