In your Purchasing Info Record (PiR), you have defined a 'Suppliers Material Number' for example. When this is no longer relevant you clear the field in the master data of the 'Purchasing Info record' using the advanced webgui tile 'Change Purchase Info records (ME12). A short time later you notice that the field has been filled again in the 'Purchasing Info record' but when you check the change log there is no change visible.

Reproducing the Issue
- Open the webgui tile 'Change Purchase Info records' (ME12)
- Maintain the Supplier, Material, Purchase Org and Plant
- Press return
- In the General Data TAB see field 'Supp. Mat. No.'
- If you clear it and save it can be filled again in the future without a change log.
Info Update flag (EKPO-SPINF). When a Purchase Order is created that meets the criteria of the info record, the PiR is picked up and assigned to the Purchase Order item automatically. If the user sets the 'InfoUpdate' flag, or it is copied from a reference item, this Purchase Order will be updated as the last PO of the PiR. Afterwards anytime that purchase order is changed, for example quantities and schedule line dates, the system will update the info record with the details from the last PO item. When these automatic updates take place no change log is captured for performance reasons.
If you do not want such updates remove the 'InfoUpdate' flag from the last PO in PiR and do not set it in other documents going forward. The 'InfoUpdate' flag is found in the material Data TAB in the 'Create/Change Purchase Order advanced' tile.
