_all is the EBS base table, which saves the EBS system data. In general, do not modify the configuration of the standard table, otherwise the system will have problems, and of course the table data cannot be deleted.
Remove the view of _all and filter out the organization according to the user environment, which is equivalent to a common base table. We use it directly as the base table.
_v is the view of EBS, which is used for Form and report. The report is for security, and the view has a security function. Generally, it is the security restriction of responsibility and profile.
_kfv, a dynamically generated view when key elastic fields are enabled, including Concacted field combinations
_dfv, a dynamically generated view when the descriptive elastic domain is enabled. When we get the description of the elastic domain subsection, we need to use the user exit function.
_tl, the base table, has a language field, and us must have it. For others, it depends on the installation. Multilingual tables will have multiple pieces of data, but the language field is different.
_vl, view, set the filter language according to the environment, so use _vl for reports.
_s, serial number, primary key for the table and other fields that need to automatically generate serial numbers.
_API, the standard package of the EBS system, guarantees backward compatibility, and generally does not need to be modified.
_PKG, the commonly used functions Package and Program in the EBS system, are provided for the required development calls, and the data of the corresponding fields can be retrieved.
_SV, Package, for Form to call.
