Regarding job failure in IBP "time series update failed"

[former_member471436]

Sometimes there will be job failures that impact the day-to-day operation and business.

common errors such as "Time series update failed with an exception for a specific version ."

the possible root cause could be :

1. Data Quality Issues: Inconsistent or incorrect data can cause the time series update to fail. This can be due to errors in the data, missing values, or invalid data types.

2. Configuration Issues: The time series update can also fail if there are issues with the configuration of the system, such as incorrect settings or missing master data.

3. System Performance Issues: The time series update can also fail if the system is underperforming due to resource constraints, such as memory, CPU, or network bandwidth.

let's talk about the time series table reach to the limitation in some cases.

When a time series table reaches its limitations, it means that the maximum capacity of the table has been reached, and the system can no longer store additional data. This can result in errors and issues when trying to update the time series data and can impact the overall performance and accuracy of the IBP system. And the Data Volume/Data Retention and system performance may contribute to the time series table reaching its limits.

to resovle this issue what we need to do is:

1. Housekeeping:

Garbage collection can be used to resolve a time series table reaching its limitations in SAP Integrated Business Planning (IBP). Garbage collection is a process that frees up memory that is no longer being used by the system, and can help to reduce the size of the time series table and prevent it from reaching its limitations. and the good news is IBP 2302 there will be an improvement regarding Garbage Collection. The HANA parameter enable_ce_execution_without_snapshot, which will be active by default in IBP 2302. By enabling the execution of calculations without snapshots, the system can process and analyze data more quickly, and provide more up-to-date results. When the config is on, it can reduce the span of GC block. GC is blocked while a long running snapshot is live. Before the configuration was introduced, the procedure execution holds a snapshot during the whole execution. Logger procedure runs, longer blocking GC. By the configuration, a procedure execution doesn’t hold the snapshot longer. Instead, it delegates the snapshot taking to the sub-operators, where they are likely to run during shorter time.

2. Prevent & Protect

To keep a close eye on the system status, EWA can be a good option and if you want to do more proactive monitoring then the Time Series Statistics card in System Monitoring app in your IBP system should be a good option.
