WinCC OA Archive Issue - All Tags Not Archived After Deleting Unused Tags

[phu.tran@biendongco.vn]

Hi everyone,

I’m currently facing an issue in my WinCC OA project. After deleting several unused tags, none of my tags are being archived anymore. The following warning appears repeatedly in the log:

WCCOAnextgenarch(118), 2025.01.09 19:26:01.771, IMPL, WARNING, 69, Database error, Could not convert value to influx line because the variable 'System1:PRO_W1_PLC10_S7_ST.value.PVLAST' has no entry inside the metadata table - forcing resync of metadata table (from System1:_NGA_B_InfluxDB)

Question:
How can I resolve this issue and restore archiving for all tags?
Could deleting the unused tags have caused this metadata error? If so, what steps can I take to fix it?
Thank you for your help!
