A story that happened with me once… After switching from release 46 to release 50, an unpleasant thing was discovered – a strange memory leak, and it happened exclusively on Mondays. The switching would be due to the fact that SP05 uses memory much more economically compared to SP04 (Note 2808956 about the Pool/L/llang/Debuggee problem). The problem occurred on Mondays immediately after running the background job /BDL/TASK_PROCESSOR. This background job is responsible for EWA purposes.
After this background job, the memory of dpserver, xsengine and docstore starts to expand:
The solution was found in note 2955475, it says that you need to update ST-PI, but in fact it was necessary to update both ST-PI and ST-A/PI to the latest version. Which is logical, because these components participate in EWA and work in pairs.
Have you set the table data elements to be output to ALV, but for some reason the old or empty column headers are being output? Database utility didn’t help? Use one of the following programs to clear the ALV buffer:
SAP Logon field entry history has a length limit. So, if the input field is 255 characters long, the input history for it will not be saved. By default, history is saved for fields that are 49 characters long. This can be fixed by setting or group policy:
Please keep in mind that you cannot fill a client with profile data, for example, SAP_CUSV (settings and options) and expect that the application data in this client will remain old. No, they’ll just wear out. When copying, you can use copy profiles that simplify selection and combination of the objects to be copied. SAP delivers the following copy profiles in the table below. The customizing and application data is deleted in the target client before copying for all profiles except SAP_USER. This is technically unavoidable.
