The Installation/Upgrade Package for Add-on "WEBCUIF" rel. "700" is not available

Hello all,

I am updating a ECC EHP3 System to ECC EHP7 and encounter the following error during the phase EHP_INCLUSION.

2 ETN085X"Calculate pure CRT Queue" "for installed Add-ons" "and already applied Support Packages" " "

3 ETN112 The OCS Package Queue is empty

2 ETN085X"Adding Add-on Installation Queue" " " " " " "

4 EPU202XEND OF SECTION BEING ANALYZED END OF EHP_INCLUSION ================================================

I was thinking if I should install this add-on beforehand. The answer negative since our system is on 700 but not 701 as specified in SAP Note 1162090 - Overview or release strategy for ABAP add-on WEBCUIF

Any idea on how to proceed ?

Thanks.
