Urgent case during Go-Live : Material issuance and receive

HI experts,

Good day

We have uploaded opening balance and master data for a store as of May 31.

As a soft go life, We would like to use the system (S4hana) for issuance and receive ( because we don't have another system to track the inventory transactions) while we still didn't upload the back log transactions of June 1 to July 31.

Our supposed Go-Live date was Aug. 1,2022

Is that possible?

I really appreciate an expert opinion for the urgent case we currently face.

Thank you so much for the support

Regards

Mahmoud
