What is the best way to generate FINITE schedule using PPDS heuristics for 3 level BOM and fix peg

I person 3 level BOM (FG-->Semi level 1 - Semi level 2) 

I americium moving PPDS heuristics successful pursuing bid successful S4 (eppds) 1809

1. SAP_PP_LLC (stage numbering)

2. Product readying (Comp acc Llevl Code)  - ie.MRP run

3. and past SAP_PP_019 (fix pegging)

Then 

4. Run Sequence bottommost level utilizing setup radical utilizing transcript of sequencing heuristics

5. Run Bottom up (SAP_PP_009) astatine Semi level 2

6. Run Stable guardant heuristics (SAP_DS_01) for generating finite schedule 

(Tried to tally measurement 6 earlier 5 also)   

But NOT getting finite docket and immoderate orders are thrown retired of PPDS skyline (one twelvemonth out) though determination is simply a batch of capableness earlier that ...some resources are inactive overloaded  (btw each resources are defined afloat restricted finite)

Fixed pegging is progressive successful planetary customization and turned for products and mounting successful heuristics to see it

Any ideas?

I americium good trying a antithetic heuristics arsenic agelong arsenic I get finite schedule

Please suggest immoderate options

Thanks
