Transportation lane not passed to optimiser

[S_Arora]

Hello,

Iam in embedded S/4 HANA 2023.

Issue is i cannot do optimiser planning  for FU since T lanes are not passed to optimiser. T lanes exist based on locations and T lanes validity is within Planning horizon and dates in FU are also within Planning horizon. T lanes exists for location sp_1710 to sp_1720 and from SP_1720 to customer 17386001. So in FU there are two stages from 1710 to 1720 and 2nd stage from 12720 to 17386001. no block in FU

Selecting  both stages or only one stage of FU and clicking on "optimiser planning with all resources"
 gives "optimiser failed" error. Below screenshot shows That T lanes are not there in RCC_LOG

What could be issue?

Hello

Can you please ask your dev team to verify once if lanes are filled and passed in the context of Preprocessing.

Best Regards,

Hello,

You could try path finder. It will help understand what is the problem in these locations. Probably you have that problem because of transportation lane MTr and optimization used MTrs are different. You should check first that one. The second thing is fu date should be in transportation lane validity period.

Also if you have more reasource with different capabilities but same distance and same duration between two locations you should create transportation lanes with superordinate MTr.

Some additional information would be helpful:

The report /SCMTMS/FIND_TN_PATH is used in SAP Transportation Management to determine if a transportation network is correctly set up to find a path between a specified source and destination. To use it, execute the report in SE38, enter the source and destination locations, and select the 'Determine Path' radio button. After executing the report, you can observe the results, which may show a direct lane or paths with multiple intermediate stops, depending on the search depth you adjust.
