IDS ford problem with Ecu number

Hi, i have problem with entering Ecu number in IDS, 
i want to change calibration, so after autodetect i choose that selection is not correct, then software asks for pcm part number, or calibration number or tear tag code...
i have only data from pcm sticker... 0281 012 857 WE07 WE0718881B, the „WE07” is not recognized as correct tear tag, 
and IDS requires pcm part number with 12a650/12k532 in the middle, 
and i have no idea how to enter pcm part number correctly... 
the car is 2008 ford ranger 3.0 tdci

Thanks in advance !
