Create Transfer order from Transfer Requirement number

Hi Experts,

I want to create TO from TR. There is three function module:

L_TO_CREATE_SINGLE

L_TO_CREATE_TR

L_TO_CREATE_MULTIPLE.

My requirement: Kitting process

1. Create TR from old TR through BDC. Tcode is:LB01. New TR has movement type 908.

2. Change the status of old TR through BDC. Tcode is:LB02.

3. Create TO from new TR. Here I used BDC. Tcode: LT04.

I have multiple line items for single TR.

My FS owner asked to use above function module to create TO.

I checked all. But not sure which one is best. Kindly Suggest.

Thanks in advanced...

Regards,

Arindam Samanta.
