Pricing Procedure for STO Schedule Aggreement

Dear All,

I am creating the STO order using the TCODE: ME37. When i click the conditions tab i am getting the following error message Not possible to determine a condition type

Message no. 06658

I have done the configuration in SPRO. MM->Purchasing-> Conditions->Define Prce Determination Process->Schema Determination-> Determine Schema for Stock transport Order.

I have defined for the document type LU and UB. I am getting error only for LU. When i create a STO using ME27 for the document type UB, i am not getting any error. The calculation schema is picked correctly.

Kindly guide me to create a STO order using the TCODE: ME37 with the calculation schema.

Thanks
