 ====== Merge Regional Categorical Maps ======
 ===== Description =====
-This functor merges regional categorical maps in to a single map.
+Rebuilds a single categorical map by merging together all the regional categorical maps that [[Regional Categorical Map]] registered under a given name in the same region manager.
 ===== Inputs =====
-^ Name ^ Type ^ Description ^
+^ Name  ^ Type  ^ Description  ^
-| Global Map Name  | [[Name Type|Name]]  | Name of the regional categorical maps specified in functor “Regional Map”.  |
+| Global Map Name  | [[Name Type]]  | Name under which the regional categorical maps to merge were registered by [[Regional Categorical Map]].  |
-| Region Manager  | [[Region Manager Type|Region Manager]]  | This is internally linked by the “Region Manager” container.((Since Dinamica 1.9.x, this input is no longer optional))  |
+===== Optional Inputs =====
+^ Name  ^ Type  ^ Description  ^ Default Value  ^
+| Merge Non Region Cells  | [[Boolean Value Type]]  | If true, cells located outside a region's mask — including its extra border — are merged in as well. If false, those cells are ignored. Merging two cells only works when they carry the same value, or when one of them is null.  | No  |
+| Region Manager  | [[Region Manager Type]]  | The region manager to read. When this functor is placed inside a [[Region Manager]] or [[Region]] container, this port connects to that container's region manager automatically.  | Provided automatically  |
 ===== Outputs =====
-^ Name ^ Type ^ Description ^
+^ Name  ^ Type  ^ Description  ^
-| Global Map  | [[Categorical Map Type|Categorical Map]]  | Mosaic categorical map.  |
+| Global Map  | [[Categorical Map Type]]  | Mosaic of the regional categorical maps registered under Global Map Name.  |
 ===== Group =====
-[[Functor List#Region|Region]]
+[[Functor List#Region | Region]]
+===== Notes =====
+This functor raises an error if no [[Regional Categorical Map]] registered a map under Global Map Name in the same region manager.
-===== Notes =====
+Merging cells outside the region masks raises an error if two different regional maps disagree on the value of the same cell — that is, both give it a non-null value, and the values differ.
-This functor allows several regional categorical maps to be merged in a single mosaic.
+Placing this functor inside a [[For Each Region]] container raises an error, since the region manager that container exposes does not store regional maps — it only splits a map into regions, it does not collect them back together. Use a [[Region Manager]] (or [[Region]]) instead, with [[Regional Categorical Map]] registering each region's map inside it.
