I'd like to find a field available in ECC that could store an identification number from an external system.
We already use most of the customer master field such as Search Term 1 and Search Term 2.
I saw in SPRO, the identification numbers, but even after creating a new one (Z001), I could not display it in the customer master.
Which field would you recommend to use? Do you know if we could display the identification number tab in XD03? Or, could we use another field such as Tax Number 1 or Tax Number 2? (Even though we don't use them currently, we don't really like using a tax number field for another purpose).
Thanks in advance for your feedback,
