Claim Elements
The level of claiming is at the 'primary' element level. Examples of primary element types are SITE, ZONE, EQUI, SUBE. Examples of non primary elements are primitives such as BOX. When you need to modify a non primary element then the first primary element up the hierarchy must be claimed out. E.g. to modify a BOX, then the owning EQUI or SUBE must be claimed.
When working on multiwrite DBs, users may either explicitly claim elements to work on, or let the system implicitly claim elements for them. The implicit claim will occur at the point of making a modification.
There are a number of reasons why an element may not be claimed:
1.
The element is claimed by another user
2.
The element is claimed by an extract
3.
The element has been changed since this user last did a GETWORK or SAVEWORK. To remedy this, you must do a GETWORK first.
If a list of elements is claimed, and some in the list fail, then the remaining elements will still be claimed.
