Can a member of a Branch Presidency set up ministering districts, companionships and assignments? If so where do I go and how do I do it?.
The LCR Access Table (in LCR, click on "Other=>Access Table") shows that the Branch President, his counselors, and his clerk each have access to all of the Ministering functionality. However, in GHB 21.2, the responsibility for organizing ministering assignments clearly falls with the EQ and RS Presidencies, and not with the Branch Presidency.
That said, it may be that the EQ & RS have organized the ministering assignments, but your Branch President feels like it's best if a member of the Branch Presidency enters the information into LCR instead of the EQ or RS leaders. In that case, the ministering information is available in LCR under the "Ministering" tab. However, be aware that even if the Branch Presidency were to enter this information in LCR, going forward it would be best to have the EQ/RS take ownership of entering future modifications, to offload this from the Branch Presidency so they can focus on their core responsibilities.
